Abstract: This work aimed to evaluate the physiological parameters, the biomass flow, and the productive characteristics of the grasses BRS Piatã and BRS Paiaguás at different levels of water supply in the semiarid region. The experiment was carried out in the dry season, in S...
Abstract: The purpose was to evaluate structural characteristics of pasture, behavioral aspects and physiological parameters of sheep finished on irrigated Tamani grass pasture under continuous stocking, using castor bean cake as alternative input. Structural characteristics of the pasture were assess...
Abstract: Livestock production in semi-arid areas has been unpredictable due to climate variability, mainly rainfall. This study aims to simulate rangeland production variability aff ected by rainfall over time and relate it to an adjusted carrying capacity, using forage stock to maximize&#x...
Abstract: Phosphorus (P) is one of the main nutrients capable of increasing yields of tropical grasses. The definition of adequate P fertilizer rates can contribute to improving forage production of pastures. However, the efficiency in the response of different genotypes of Urochloa mos...
The objective of this study was to morpho-agronomically characterize Urochloa sp. accessions from the forage collection of Embrapa Caprinos e Ovinos, aiming to identify the most divergent accessions to support the selection of materials better adapted to cultivation under semi-arid conditions.&#x...
O farelo de mamona possui grande potencial para ser empregado nas dietas de pequenos ruminantes devido ao seu elevado teor proteico (40% a 48%). Objetivou-se avaliar o desempenho produtivo de cabritas alimentadas com farelo de mamona. A pesquisa foi realizada no centro tecnológico ...
